 The history is based on the `ReplicaSets`/`ControllerRevisions` still in the system. I.e., the history is limited by the
 configured `revisionHistoryLimit`.
 
 By default, all revisions are printed as a list. If the `--revision` flag is given, the selected revision is printed
 instead.

 This is similar to using `k get replicaset` or `k get controllerrevision`, but allows easy selection of the relevant objects and returns a sorted list.
 This is also similar to `k rollout history`, but doesn't only print revision numbers.

 The `k revisions diff` command uses `diff -u -N` to compare revisions by default.
 It also respects the `KUBECTL_EXTERNAL_DIFF` environment variable like the `kubectl diff` command.
